Jackson Martinez has once again emerged as a target for Arsenal this summer, according to the player’s agent. The striker market is looking thin at the moment for Arsenal, who need someone who is capable of scoring 20 league goals at least next season. But Martinez has been linked with a move out of Portugal for much of the past year, with clubs around Europe impressed by the Porto forward’s scoring record. The Portuguese club are notoriously difficult to negotiate with, which makes it difficult to see Wenger moving for the Colombian. But Wenger may well be convinced if the forward has a good World Cup. Based on stats alone – 20 goals in 30 league games last season – he’d be a good buy for the club.
